“…Incidence of cutaneous adenocarcinoma of sebaceous gland was reported in jaguars and was attributed to age and husbandry practices in captivity [34]. The neoplasms reported in jaguars were thyroid adenoma and adenocortical adenoma, ovarian cystadenocarcinoma, haemangio-endothelioma, glucagonoma, squamous cell carcinoma of the tail, visceral mast cell tumor, and mammary tumor [5].…”

“…Prevalence of these diseases vary with age [2] and management practices [3,4]. Neoplastic proliferations of benign and malignancy are one of the common causes of morbidity and mortality in wild felids including jaguars [5]. Sebaceous adenomas are common benign tumors found more often in all domestic animals with higher prevalence in middle to older age dogs and cats [6].…”

Aim: A captive male jaguar (Panthera onca) was anaesthetized for surgical excision of a tumor at the left belly fold under xylazine-ketamine immobilization and propofol anesthesia. The objective was to assess the dose of xylazine and ketamine required to abolish ear flick reflex for safe approach when the jaguar was under chemical immobilization and efficacy of propofol induced anesthesia.Materials and Methods: A male jaguar (P. onca) aged 14 years and weighing approximately 90 kg was subjected to chemical immobilization using a combination of xylazine and ketamine using a blow pipe. The jaguar was approached after the absence of ear flick reflex and transported to zoo Operation Theater. Propofol was administered intravenously to induce and maintain anesthesia. The tumor was excised using thermocautery and subjected to histopathology.Results: Ear flick reflex was stimulated at 5 and 10 min after immobilization and observed shaking of head and movement of fore limb following administration of xylazine and ketamine. Dose of xylazine and ketamine required for chemical immobilization, characterized by absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively, and was achieved in 13 min. The surgical plane of anesthesia was maintained for 11 min following administration of propofol at a dose of 2 mg/kg body weight intravenously. The jaguar recovered in 41 min following surgery. The excised tumor was confirmed as sebaceous adenoma on histopathological examination. The animal recovered uneventfully, and no recurrence of the tumor was noticed in 3 months follow-up period. Conclusion:The total dose xylazine and ketamine required for chemical immobilization with absence of ear flick reflex was 1.0 and 3.5 mg/kg body weight respectively. Further, administration of propofol intravenously, at a dose of 2 mg/kg maintained anesthesia for 11 min. Histopathological examination of the excised tumor at the belly fold was confirmed as sebaceous adenoma.

ResumenHan sido observados diferentes tipos de neoplasias en distintas especies de animales, las cuales pueden agruparse según el tejido de origen y su grado de malignidad. Pueden ser de origen epitelial, mesenquimal, de células redondas o de células productoras de pigmentos. De acuerdo con el grado de malignidad, se clasifican como benignas y malignas. Los carnívoros constituyen un orden perteneciente al reino animal, dentro del cual se encuentran varias familias. Según la interacción que tengan con el medio ambiente y la exposición a agentes contaminantes, virus y situaciones estresantes, algunos individuos de ciertas familias pueden desarrollar un tipo de neoplasia. Tanto en félidos como cánidos, se han encontrado mayor incidencia de neoplasias de tipo epitelial involucrando el sistema tegumentario; en pinnípedos el sistema mayormente afectado es el tracto reproductivo. Existen pocos reportes de neoplasias en prociónidos y mustélidos, lo que puede sugerir una mayor resistencia genética a la presentación de neoplasias por parte de estas familias, o a una exposición menor a cancerígenos.El propósito de esta revisión es conocer las neoplasias más frecuentes en especies salvajes, ya que estas sirven como centinelas del ecosistema y ayudan a determinar posibles contaminantes carcinogénicos en el ambiente. Conociendo el grado de similitud en la génesis y progresión tumoral en humanos, con relación a la vida salvaje genera oportunidades de tratamiento y conservación y pueden servir como centinelas efectivos para problemas de salud pública. Además, su importancia en favorecer y fortalecer mecanismos encaminados para la salud y conservación de especies silvestres, ya que pueden ser mermadas considerablemente a causa de este tipo de enfermedades.Palabras clave: animales silvestres, cánidos, enfermedades neoplásicas, félidos, prociónidos, mustélidos. AbstractDifferent types of neoplasia have been observed in different species of animals. Neoplams are divided by the tissue of origin and its degree of malignancy. They may be of epithelial, mesenchymal origin, of round cells and of pigment-producing cells. According to the degree of malignancy, they are classified as benign and malignant. Carnivores constitute an order belonging to the animal kingdom, within which are several families. Depending on the interaction they have with the environment and exposure to pollutants, viruses and stressful situations, some individuals from a different family may develop a neoplasia. In both felids and canids, we have found a higher incidence of epithelial neoplams involving the integumentary ARTÍCULO DE REVISIÓN/REVIEW ARTICLE
